| APPLET | SOURCE | DESCRIPTION |
|
| Varying Moving Averages | Wolfram Demonstrations Project | Shows differences as period for moving averages is varied. Requires download of Mathematica Player as well as demo itself, good for classroom demonstration. more |
| Data Smoothing | Wolfram Demonstrations Project | For several data sets, shows differences as period for moving averages and moving median is varied. Requires download of Mathematica Player as well as demo itself, good for classroom demonstration. more |
| Moving Average | CAPDM Tutorial Applets | For several data sets or randomly generated data, shows differences in moving averages as period is varied. more |
| Forecasting by Smoothing | A Collection of JavaScript E-labs Learning Objects (Arsham) | For series with up to 80 observations, calculates forecasts and errors using: moving averages and weighted moving averages for specified period, single, double and triple exponential smoothing for specified alpha value, and Holt's linear smoothing for specified alpha and beta. more |
| Exponential Smoothing | CAPDM Tutorial Applets | For a specific data set, shows differences as smoothing constant is varied, also shows differences in moving averages as period is varied. more |
| Forecasting Applet | McGraw-Hill | Users can view, adjust or add points to the example series or enter up to 20 observations of their own data, can employ exponential smoothing or trend adjusted exponential smoothing with various smoothing constants, or use the linear trend equation or simple linear regression and observe forecasts, MAD, and MSE. more |
